HENRY G. HUGHES, OF MENDN, UTAH.

l AUTOMOBILE Loox.

Application filed August 11, 1926. 5 Serial No. 128,682.

My invention relates, to locks for auto-yl mobiles and has for its object to provide a new and eiiicient lock 'For an automobile which will be safer `than the Ordinary .key lock and which will beoperated b'y the driver oi the car as a combination lock. y y

A further Object is to provide a combination lock for automobiles which will lock both the lights and the .ignition switches.

A still further Objectis to provide an economically constructed combination lock for the ignition and light switches for an automobilezwhich will have less parts in its construction and which will not get out of order. i

These objects lUaccomplish with the device illustrated in the accompanying drawings in which similar numerals and letters ot reference indicate .like parts throughout the several views and as described in the specification forming apart ofvthis application and as pointed ont in the appended claims. ,i Y y In the drawings of which have shown the best and most preferred manner Oi' building my invention, Figure l. is a front view of my lock. `liligure 2 iena top view of the same. Figure 3 is a front view of the front plate used in my lock. Figure 4 is a front view ot the insulation plate used on the rear of my lock. Figure 5 is an edge view of the dial. Figure 6 is a front view of the dial.

Figure 7 is a plan view of the switch. Fig ure 8 is a section on line 8-8 of Figure 1. Figure 9 is a plan view ot the locking plug. And Figure 1() is a section on line lll-10 of Figure 9.

1n the drawings I have shown the casing in which my lock is mounted and operated as A. 0n the 'front and closed side of said casing 1 providea plate B in. which the dials D are mounted and through which plate B the lock sleeve S is passed. Ont-he rear side Ot' the said casing A .l provide an insulation plate E which closes the'open side of. the casing A. Bolts 1 are passed through the holes 2, cut in all oi' the plates and the casing A to secure the entire device together. The said plate B has two spaced apart holes 3 and el cut therethrough and on the back side of said plate the holes are bored larger, as at 5, and in which holes the dial plates D are rotatably carried and Operated. A check or indentation 6 is made in the plate B on the upper side of each hole to mark the combination position. The dial plates D are made of lat circular sheets of metal with the back side D2 of larger diameter than the front, and havev a` knurled turning knob D1 provided on `the trontside thereof by which they may be turned. Letters 7 are printed on the face of the dials D and smaller marks or indentations 8 are made in the face of. said dialsdividing the space in between the letters into equal parts to make it look as though more combinations were possible. i Holes 9 are bored centrally through said dial plates D and through which holes the switch posts 10 are carried and rotatably Operated. A4 slot 11 is cut in the back and enlarged side D2 of the dial plates D through which a guide or catch 12 on the sleeve passes when the combination has been worked. A similar groove 13 is cut in the edge'of a switch plate 14, which plate is secured to the said post 10, and another plate Oi insulating material 15 is se cured to the said plate lll. A switch spring 16 is secured to a cross plate 17, which is in turn secured to the said insulation plate 15. Hand levers 25 are. secured to the free ends of the post 10 bywhich the switches may be operated. Wire connections 18 are provided on the back side oi the said plate E and are connected with Contact points 19 secured to the front side of the plate E, as shown in Figure 8, and with which point the springs 16 are brought into contact when the switches are turned. Both ot the dials D are alike except that the slots 11 may be cut at different places on the periphery of the said dial plates. A locking sleeve S is passed through the entire casing A and the plates B and C through holes 2O bored through the entire assembly, and each of the said holes Q0 has grooves or notches 21 cut in its periphery through which notches 9.1 the guides 12 pass when the locking sleeve is being changed. The said locking sleeve S has two guides 12 secured therein and said guides are held in place by a spring 22 secured inside the said sleeve S by the pin 23. A spring 26 is provided on the said sleeve S to normally hold said sleeve in place in the hole Q0. A plug 27 is secured to the free end of said sleeve S to normally hold said spring on said sleeve S.

The operation of my device is as follows:

When it is desired to lock the ignition and light switches of the automobile, the locking sleeve. S is pulled outwardly and turned a quarter turn so that the guides .12 will tit into the cross slots 2l. The sleeve S is then pushed into place again andthe combnations turned on the dials D until the slots l1 are not in alinement Withzithe guidestlQ, or the slots 13. The switches Will then be locked. To unlock the switches thec'on'ibination numbers on the dials D Will be turned until the predetermined combinationy is in laceand the slots -llare `again in alinernent vvitlftlie guides 12 and the slotsfl. The sleeve yS may then be drawn out' and turned a lquarter 4turnfand:pushedv back into the former position ,ag-ain.v The, switches Will then be Yfree to move as desired. The .spring on tfljieslee-veS hol-ds the saidlsleeve norinally against the plate VB, as shown in Figiire '2, Whichfigure also shows by dotted `lines the sleeve `Spdrawn out.

Having thus ,described my invention7 I desire to secure by Letters Patent and olaimz# l. 1n a look Vfor automobiles the combination 'of a casing having holes bored therein with slots atfright anv les to each other in the peripherie's"or' thenoles;` a plate secured in front of said casing, With holes andslots therein similar tothe holes in said casing and in alignment: therewith; an'insulated Cover over v the Arear of'sayidy casing` having a eentral "hole bored therethrough in alignnient With the vcentralflioles ,in the easing anidnplate andvvitli slots Lat riglitangles `to each other ein the peripheryfof said hole; dials operable theholes in said plate with the rear sidey of eah of greater diameter thani'the .front sideandhavng slots cut in the enlarged rear side ofsaid dials through Which guide members areslidable when all ofthe slots are in alignment; turning knobs `Qneaeh ofsaiddials with holes bored centrally therethrough; a switch post operated 4through .the holes in said knobs; a switch attached thereto; contact members secured through said insulated cover adapted to be brought into Contact with said switches by turning said posts; a locking sleeve voperable through 'the central hole said casing', plate andfcover; andlguide members `carried in said sleeve,V o rable intheslot's inl the periphery of "t iewholesv in the casing, plate and cover adapted to hold the llocking 'sleeve pigra' ,in tlaei'oek;
